Be it known that I, WILLARD A. VAN

:BRUNT, aicitizen o f the UnitedStates, residing at :Los Angeles, in the county of Los Angeles and .State .of California, have ,inventedcertainnew and useful Improvements in Bearings for Gmund-WorkingDisks, of I which the :followingis aispecification.

' BEARING FOR GROUND-WORKING DISKS.

Application filed :April 1, 1918. Serial 1105225321.

wthroughsthe axle as shown in Fig. 5. The =zinslde of-eachsupporting member 1 is preferably providedkwith a-tapered recess 6, as 1 :shown inEigs. 4 and 5 and the ends ofthe axle extensions 3 are likewise tapered to .fittheserecess'es- Each supporting member also Fhas a lug 7 fittingia recess 8 in the end of each axle extension :to prevent the axle from :turning; one ofthe supporting members having a lateral "projectionr9 which projects' over {the headof the bolt to likewise prevent the bolt from turning.

ThediskelOhassecured thereto hub mem- :bers 1:1,each 'hub member being formed with pa peripheral flange 11 provided with integrally formed rivets 12 and alternating openings 13, the rivetsof each hub member projecting through the disk into the open-t ingsvof theiflange of the opposite hub member to :firmly secure-the hub and disk together.

Paper washers (not shown) are preferably ainsertedbetween the hub flanges and the disk to make an oil tight j oint;

The hub sections are shaped to conform themselves to the exterior of the enlarged portion of the axleand to that end are ex tended-inwardlyas indicated at 11 so as to project in closeproximityto the axleexten =sions :3, as shown in Fig. 5. Caps 14 are provided on each "sideof the hub for the purpose of excluding dust, these caps being spring-pressed against the "walls l1 ofthe hub by springs 15, interposed between the caps-and the supports 1, the caps having small projections 16 which fit grooves 17 in the axlerextensions to prevent .thecaps from "turning. Theaxle extensions 3 are provided with openings 18 through which oil may be inserted into "the interior of the chamber of the :axle, these openings being ordinarily closed'by thecaps '14:, the caps being pressed back against the :tension of the springs in qorder to expose the openings for filling purposes. The central chambered portion of theaxleis-provided with openings 19 to permit the oil on the interior of the chamber to find .its way to the wearing surfaces between the axle and the hub.

By referring to Fig. 5 it will beseenthat the bottom of the chamber in the axle extends well below those portions of the bearing surfaces from which the oil can escape, and that the hub incloses the wearing surface of the axle to a point above the bottom of the chamber; the lowest point on the bean ing surfaces which would permit the escape of the oil being that placewhere the smallest diameter of the hub section meets the axle extensions, as indicated at 20 in Fig. 5.

From this arrangement it will be apparent that it is possible to have the interior of the bearing contain a considerable quantity of lubricating oil-"which will find its way t the wearing surfaces through the openings 19 and gravitate alon the outer sides of the chambered p rtion of the axle and the inner diskhub journaledon said axleabout said chamber, said hub being extended inwardly toward, the axis of said axle so as to inclose the bearing surface of said axle to" a pcintabove the bottom of said chamber in the working' position of the parts, said chamber having an oil passageway leading to the bearing surfaces between the same and said hub.

2'; I a bearing of the characterdescribed, an axle provided with an enlarged on chainber, and a disk hub jouri'ialed on said axle about said chamber with the smaller portion of said axle projecting throughsaid hub, said hub being extended inwardly toward the axis of said axle and about the smaller pbrtio'n thereof so as to inclose the bearing surface of said axle to a point above the bottom of said chamber in the working position of the parts, saidchamber having an oil passageway leading to the'bearing surfaces between the same and said hub.

3. In a bearing of the character described, an axle provided with an enlarged circular centrally-arranged chambered portion, a bifurcated support between which said axle is clamped, a disk hub rotatably mounted upon the chambered portion of said axle and having its walls extended inwardly toward the axis of said axle so as to inclose the wear ing surface of said axle to a point above the bottom of the chambered portion thereof, the chambered portion of said axle having an oil passageway leading to the bearing surfaces between the same and said hub.

4. In a bearing'of the character described,

an axle formed with an enlarged circular centrally-arranged chambered portion and reduced hollow extensions on each-side there of, a bifurcated support between which said axleis clamped, and a disk hub journaled on the enlarged portion of said axle with its sides extended toward the axis of said axle to a point above the bottom of the chambered portion of said axle, saidchambered portion having an oil passageway leading from the bottom thereof to the bearing surface between the sameand said hub.

--' 5. In bearing of thecharaetet described,

an ax'le formed with an enlarged circular centrally-arranged chambered portion and reduced hollow extensions on each side-thereof, a bifurcated support between which said axle is clamped, a disk hubjournal'ed-on the enlarged portion of said axle with its sides extended toward the axis'of "said-- axle to a point above the bottom of'the chambered portion of said axle, said chambered portion having an oil passageway 'leadin g" from the bottom thereof to the te ring 'surface between the same and Shanta-ands spring pressed cap' bearing against-said on each side thereof.

ofthe character described,

6.' In a bearing an axle provided with a large circular centrally-arranged chambered";portion-and reduced side hollow extensions, a bifurcated T support, a bolt extending throughisaid .sup port and axle'to clampithe axle in position, interlocking projectionsbetween said support and axle to prevent the'axle'fromturning, 'a disk hub journaled upon the enlarged portion of said axle and inclosing the sides of the same; the side walls ofsaidhubbeing extended toward the axis of said axle to a point above the bottom ofthe chambjered portion thereof, and an oil passagewayleading from the chambered portion'of said axle to the bearing surfaces betweenthe same and said hub;

an axle provided with a large circular cen-' trallyfarran ed chambered portion reduced side iollow extensions, emanated support, a bolt extending through 'saidjsupport and axle to clamp the axle in position,

interlocking projections bet-ween said support and axle to prevent the axle from turning, a disk hub journaled upon the enlarged portion of said axle and inclosing'the' sides of the same, the side walls of saidhubbeing extended toward the axis of saidaxle to a I point above the bottom of the chambered portion thereof, an oil passageway leading from the chambered portion of said axle to the bearing surfaces between the same and said'hub, and a spring presseddnst cap on an innerbearing member and an outer bearing member, the inner member being provided an oil reservoir, said outer'member surrounding sald reservoir and belng extended toward the axis of said reservoir 10 member to a point above the bottom fof the reservoir thereof, said reservoir having an oil passageway leading to the bearing surfaces between said bearing members.

In testimony whereof, I have hereunto set my hand this 14th day of March, 1918.
